Independent Front Suspension Squat when Braking

Okay so, my default vehicle is a Roamer XT but I made a custom I6, custom tires, and custom suspension, and custom transmission/torque converter. However, the front suspension literally squats when I press the brakes, which never used to happen and doesn't happen with any other vehicle, oddly enough it only happens with the heavy duty brake rotors installed. (I did not modify the brakes)

Does anyone else have this issue?

EDIT: I forgot to mention this occurs when the car is stationary/standing still. As if the front suspension is being pulled down. I also finally got the video to post.

EDIT #2: Okay so looking at the D15, with the same Heavy Duty Brake rotors, it too faces the same issue, not as badly, but it's there.

I have now also posted a recording of what happens in the Beam Stress Visualizer when the brakes are applied.

 

Thats how cars are in real life, and it happens to all the other vehicles in game to some degree.

 

No, I mean when it's stationary. Standing still the car suspension is pulled down when I press the brakes.

 

That is odd and definitely doesn't happen in real life. I can't really test that right now, but I will next time I play the game.

 

that sounds like a bug to me Yamiicherry probably something to do with the mods you are running

 

Well the mods I'm running are from the game, I just took the files from the game and modified the beamDeform and beamStrength. Nothing to do with the brakes though.....

 

that sounds like a programming thing not something I am use to

 

What it could possibly be... possibly... is that one of the beams in your suspension its right on the verge of existence...

Basically when your not standing on the brakes, it is stable and nothing happens, but when you stand on the brakes, it starts jittering and vibrating, and somehow is changing the shock position. My suggestion, go into debug mode, turn on you beam stress visualizer, turn on simple nodes, put the game in slow motion, and then hit the brakes... what do you see? If you see nothing much change, then that probably isn't it. If you see a spazme of colors and a node or two wildly shaking about, then that is your issue.

Just saying it could be this and that's something to check. I have experienced similar things when making mods, and this is almost always the issue.

 

I'll check this out when I get home later. You're probrably right. I do notice when you zoom into the rim while pressing the brakes that the cap that hides the lug nuts starts jittering slightly, it's not noticable unless you zoom in.

 

do the brakes also heat up enormously, even when stationary? my d-series front brakes do that, i don't drive the roamer much but i think it's the same chassis

 

This is also correct, idk why but they fade even when staying still.

 

That means that something has an instability in it.... be it node weights, wheel weights, too high brake force, too high damping (or too low damping), too high spring... could be a lot of things... but it's definitely from and instability somewhere...

 

Only time my car did squat when pressing brakes at stationary was after some crash, so I'm with atv_123 here, there must be some beam missing or some kind of at the edge value causing structure to be unstable, so when brake force is applied it starts to bug out.

 

I have posted in the OG post a video of what happens in the Beam Stress Visualizer.

 

Yep, no doubt about it... you have an instability somewhere in the front suspension causing your issue.

 

What could cause it though....all I did was tighten the springs and shocks a little and made the frame/suspension components stronger.

 

Pretty much exactly that...

The Devs have the parameters fairly finely tuned, so if you just increased the spring rate of the beams (to make them stronger/stiffer) without adjusting damping or the weight of the nodes they are connected too, you will run into these issues. So essentially, you might have a bit too much spring or a bit too much damping for things to work quite properly. So you need to isolate what part is causing the issue, and then go about adjusting the spring/damp of those beams to compensate for the instability (usually by lowering the damping rate, but sometimes by lowering the spring rate)
